Characterization　of　human　body　channel　is　a　necessity　to　pave　way　for　the　practical　implementation　of　implant　communication.　Considering　there　are　few　investigations　on　the　characterization　of　incident　wave　propagating　at　an　arbitrary　angle　to　human　tissues,　this　paper　applies　an　analytical　model　of　wave　oblique　incidence　onto　multilayered　planar　lossy　tissues　to　evaluate　the　far-field　EMFs　and　PLs　of　body　channel.　With　this　model,　EMFs　and　PLs　of　both　TM　and　TE　wave　oblique　incidence　at　different　angles　and　frequencies　in　out-to-in　and　in-to-out　propagations　are　calculated.　A　FEM　model　and　a　measurement　on　porcine　tissues　are　also　carried　out.　Comparing　with　simulation　and　experiment,　the　analytical　results　of　PLs　have　the　maximum　differences　of　0.03　and　1.0　dB,　respectively,　in　out-to-in　propagation　and　of　0.09　and　1.7　dB,　respectively,　in　in-to-out　propagation.　Therefore,　the　analytical　model　is　accurate　and　indicates　the　mechanism　of　EM　wave　propagation　in　body　channel　theoretically.
